[0047] As mentioned in the background technology, 5G NR proposes an advance measurement mechanism. The terminal obtains the target frequency list (list) and physical cell identification (PCI list) that need to be measured through the Radio Resource Control (RRC) release (RRC Release) message or system message, and reports the measurement results in the RRC establishment (RRCsetup) and RRC recovery (RRC Resume) processes respectively. The measurement results are reported subsequently to facilitate the base station to perform subsequent carrier aggregation (CA), dual connectivity (DC) and other configurations.

[0048] For idle terminals, as shown in Figure 1, the network includes advance measurement configuration information (e.g., PCI list) in the RRC release message. The terminal then initiates a two-step random access process: the terminal sends Message 1 (Msg1), a random access preamble (Physical Random Access Channel (PRACH) preamble), to the network; the network sends Message 2 (Msg2), a random access response, to the terminal.

[0049] The terminal may report measurement results during the RRC establishment process: the terminal sends message 3 (Msg3), RRC setup request (RRCSetupRequest) to the network; the network sends message 4 (Msg4), RRC setup (RRCSetup) to the terminal; the terminal sends message 5 (Msg5), RRC setup complete (RRCSetupComplete) to the network, which indicates that measurement results are available to report (indication of measurement result available);

[0050] The network requires the terminal to report the measurement results in the terminal information (UE information) request reporting process: the network sends an RRC Security Mode Command to the terminal; the terminal feeds back an RRC Security Mode Complete (RRC Security Mode complete) to the network; the network sends a terminal information request (UE Information Request) to the terminal, which includes a measurement report request (MR (Measurement Report) request); the terminal sends a terminal information response (UE Information Response) to the network, which includes a cell and optional beam measurement report (cell and optional beam MR).

[0051] Then, the network sends an RRC reconfiguration (RRCReconfiguration) message to the terminal, and the terminal sends an RRC reconfiguration completion (RRCReconfigurationComplete) to the network.

[0052] For an inactive terminal, referring to Figure 2, the terminal can report the measurement results in the RRC recovery (RRCResume) process: the terminal sends an RRC recovery request (RRCResumeRequest) to the network; the network sends an RRC recovery (RRCResume) message to the terminal, which instructs the terminal to report a measurement report; since the recovery process of the inactive state can restore security encryption, the terminal can report the measurement results in the RRC recovery completion (RRCResumeComplete) message of the process.

[0053] Then, the terminal switches to the RRC connected state (RRC_CONNECTED), the network sends an RRC reconfiguration (RRCReconfiguration) message to the terminal, and the terminal sends an RRC reconfiguration completion (RRCReconfigurationComplete) to the network.

[0054] In the existing advance measurement mechanism, the base station sends a frequency list and defines a timer and validity area. That is, advance measurement is performed within a certain time range and a certain area. This controls the range and timing of terminal measurements and reduces unnecessary power consumption.

[0055] In R18, RAN4 (the working group in 3GPP responsible for formulating technical standards for RF in terminals) enhanced the advance measurement (Scell ​​(Secondary Cell) / SCG setup (Secondary Cell group setup) / resume delay). In addition to sending the list of measurement target frequencies, a second step was added to check whether the measurement results obtained during the establishment / restoration of the connection are valid: through a predefined timer, the results obtained within the timer range are valid, and the measurement results obtained during the cell reselection process can also be reported. In addition, additional measurements are performed during the process of establishing or restoring the connection, and the ongoing measurements are reported to the network. After that, the network will require the terminal to report the measurement results.

[0056] The aforementioned early measurement mechanisms are generally targeted at 5G NR scenarios and require further enhancement to better adapt to 6G communication scenarios (or to achieve better performance in 5G NR scenarios). For example, given that 6G networks allow users greater autonomy and terminals can connect to multiple cells, the fixed and terminal-unique early measurement configurations in the existing early measurement mechanisms are clearly no longer appropriate.

[0057] After analysis, the inventors of this application discovered that one of the causes of the aforementioned technical issues is that, when configuring measurement targets, the existing technology only configures a single list of measurement targets. Regardless of the terminal's location during measurement, the terminal must measure the same measurement targets in the same list. However, in reality, measurement results for the same measurement target vary significantly depending on the terminal's location. The existing technology fails to consider the impact of terminal location on measurement target configuration, resulting in the inability to further enhance the early measurement mechanism in 5G NR scenarios, and even less adapt to 6G communication scenarios.

[0058] To solve the above technical problems, an embodiment of the present application provides an advance measurement method, including: receiving configuration information, the configuration information including at least one measurement target, the measurement target being associated with a location; and measuring the corresponding measurement target according to the current location.

[0059] This implementation provides an enhanced advance measurement mechanism, configuring different measurement targets based on the terminal's location. The terminal then determines the frequency or cell to be measured based on the different measurement targets and locations configured by the network and its current location. This allows the terminal to accelerate the recovery of multi-cell operation in an inactive or disconnected state through advance measurement, which helps reduce terminal power consumption. In an active state, the measurement mechanism can also be enhanced to reduce terminal power consumption.

[0060] Next, some basic concepts that may be involved in the embodiments of this application are explained.

[0061] Regarding 6G networks (6G communications, 6G network architecture): User-centric networks are a requirement of the 6G network architecture. User-centricity enables users to define, configure, and control network functions related to their subscribed services. User-centric 6G networks primarily utilize multiple transmission reception points (TRPs) or multiple access points (APs) to meet users' high-speed transmission needs while minimizing handoffs and maintaining continuous service.

[0062] A possible 6G network architecture is the CCU-DDU-AP architecture, which includes a cloud control unit (CCU), a distributed data unit (DDU), and a wireless access point (AP). This architecture introduces:

[0063] 1) Cloud Control Unit: Provides network management and control plane functions. This includes traditional control plane functions such as system information management related to the Access Stratum (AS) and Non-Access Stratum (NAS), establishment / maintenance / release of Radio Resource Control (RRC) connections, paging control, and security functions, including bearer management, mobility management, terminal measurement, report management, and NAS information transmission. The CCU also performs management plane functions in the User Centric Access Network (UCAN), such as terminal context management and AP management.

[0064] 2) Distributed Data Unit: As the anchor point of the User Plane (UP), the distributed data unit manages basic user plane functions.

[0065] 3) AP: Mainly responsible for antenna RF transmission. It uses low-frequency TRP to ensure wide coverage and high-frequency TRP to ensure service transmission.

[0066] For terminals, when accessing the network, they may connect to one or more APs to receive services. Existing 6G networking scenarios include low-frequency cells (APs) for wide coverage and high-frequency cells (APs) for service transmission. The wide-coverage frequency cell is referred to as the primary frequency cell, as shown in Figure 3. In Figure 3, the fill areas of varying depths represent the signal coverage of each high-frequency cell / low-frequency cell.

[0067] Regarding the air interface status of the terminal: In 3GPP NR, the terminal has three states in the air interface: RRC idle state (RRC_IDLE), RRC inactive state (RRC_INACTIVE) and RRC connected state (RRC_CONNECTED). In the idle state, terminals are not connected to the base station and only need to periodically initiate location updates, perform cell reselection procedures, and receive paging. In the connected state, terminals are connected to the network, and the network configures terminal resource blocks (RBs) and physical layer configurations, including DC operation (divided into same-frequency and inter-frequency scenarios, with at least two cells controlled by different gNBs). The network can schedule uplink and downlink data for the terminal. In the inactive state, terminals do not need to notify the base station when moving within a certain Radio Access Network (RAN)-based Notification Area (RNA). The terminal retains certain configurations (currently, the terminal retains configurations such as Packet Data Convergence Protocol (PDCP) / Service Data Adaptation Protocol (SDAP) and some low-layer configurations of the original serving cell (Primary Cell (Pcell)), but does not retain the low-layer SCG configuration). If the network needs to schedule the terminal or the terminal has data to send, it needs to migrate to the connected state and restore the retained configuration for data transmission.

[0068] There may be only one RRC connection state in the 6G network. In the RRC connection state, based on whether there is a stable physical layer channel, it is divided into two states: non-active and active. Both states are sub-states of the RRC connection state.

[0069] Non-active state: This refers to the terminal's power-saving state. The network and the terminal primarily maintain security context and bearer context, and may also have a complete DRB (Data Radio Bearer) configuration. There is no fixed physical layer channel between the terminal and the network, meaning the terminal does not maintain fixed activated air interface resources with a specific DDU / TRP. When a transmission is required, a specific DDU / TRP must be activated. For faster transmission, the physical layer configuration of the TRP can also be pre-configured and activated on demand.

[0070] Active state: This refers to a state in which the terminal can continuously transmit data. The user context is maintained, the terminal maintains a user physical layer channel with the network, and maintains active air interface resources / physical layer configuration with one or more specific DDUs / TRPs. Flexible cells are formed and managed only in the active state.

[0071] In order to make the above-mentioned objectives, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0072] FIG4 is a flow chart of an advance measurement method according to the first embodiment of the present application.

[0073] This implementation scheme can be applied to 5G NR scenarios as well as 6G communication scenarios.

[0074] In a specific implementation, the communication method provided in the following steps S101 to S102 may be executed by a chip with communication functions in the terminal, or may be executed by a baseband chip of the terminal.

[0075] The terminal implementing this embodiment may be in a 6G non-active state or a non-connected state, wherein the non-connected state includes a 5G RRC idle state (RRC_IDLE) and an RRC inactive state (RRC_INACTIVE). Of course, this embodiment may also be applicable to a connected terminal.

[0076] Specifically, referring to FIG4 , the advance measurement method of this embodiment may include the following steps:

[0077] Step S101: receiving configuration information, where the configuration information includes at least one measurement target, and the measurement target is associated with a location;

[0078] Step S102: measuring the corresponding measurement target according to the current position.

[0079] More specifically, different measurement targets may be configured according to the location of the terminal.

[0080] Furthermore, the measurement target may be selected from at least one of the following: a frequency list, a cell identifier list, a transmitting / receiving point identifier list, a wireless access point identifier list, and a transmitting / receiving point group identifier list. The frequency list includes frequency information of one or more frequencies; the cell identifier list includes identifiers of one or more cells, such as PCI identifiers; the transmitting / receiving point identifier list may include identifiers of one or more TRPs; the wireless access point identifier list may include identifiers of one or more APs; and the transmitting / receiving point group identifier list may include identifiers of one or more TRP groups, where each TRP group includes one or more TRPs.

[0081] In some embodiments, one or more TRPs included in a TRP group can be determined based on the network layout information of high-frequency APs within the signal coverage range of the primary frequency cell (also known as a wide-coverage cell or a low-frequency cell) in which the terminal is located. In the non-edge area of ​​the signal coverage range of the wide-coverage cell, the signal coverage ranges of adjacent co-frequency TRPs (i.e., adjacent high-frequency co-frequency APs) may not overlap; in the edge area of ​​the signal coverage range of the wide-coverage cell, the signal coverage ranges of adjacent co-frequency TRPs may overlap.

[0082] Furthermore, the configuration information can be carried by dedicated signaling. For example, it can be carried by an RRC release message. For another example, in a 6G communication scenario, the signaling that releases the terminal from a connected state to an inactive state can include configuration information.

[0083] Alternatively, the configuration information may be carried via system messages.

[0084] In a specific implementation, the configuration information may include a first threshold, and the first threshold is associated with the primary frequency cell. The terminal may measure the base station of the primary frequency cell to obtain a measurement result in the primary frequency cell.

[0085] Furthermore, the measurement results in the primary frequency cell can be used to represent the location of the terminal from the base station. Terminals at different locations have different distances from the base station of the primary frequency cell, and accordingly different measurement targets can be configured.

[0086] For example, the at least one measurement target may include a first target and a second target. The distance between the first target and the base station of the primary frequency cell is closer than the distance between the second target and the base station of the primary frequency cell. Step S102 may specifically include: in response to a measurement result in the primary frequency cell being greater than or equal to the first threshold, measuring the first target; and in response to a measurement result in the primary frequency cell being less than or equal to the first threshold, measuring the second target.

[0087] Furthermore, the measurement results can be based on signal quality characteristics such as RSRP and RSRQ.

[0088] In a typical application scenario, as shown in Figure 5, the configuration information can configure two measurement targets (a first target and a second target) within the signal coverage range of the primary frequency cell. The first target is selected from a high-frequency AP that is closer to the base station of the primary frequency cell, and the second target is selected from a high-frequency AP that is farther away from the base station of the primary frequency cell. Furthermore, the configuration information can also configure a first threshold.

[0089] The terminal measures the reference signal (RS) sent by the base station of the primary frequency cell, which may include SSB (Synchronization Signal Block) or CSI-RS (Channel State Information Reference Signal), etc. If the measurement result is greater than or equal to the first threshold, it indicates that the terminal is in an area with a radius x (corresponding to the area circled in dotted circles in Figure 5) with the base station of the primary frequency cell as the center, such as the position of terminal A shown in Figure 5. The specific value of the radius x is associated with the specific value of the first threshold, and the unit of x can be meters or kilometers. At this time, the terminal uses the first target as the measurement target for advance measurement.

[0090] If the measurement result is less than (or equal to) the first threshold, it indicates that the distance from the terminal to the base station of the primary frequency cell is greater than x (corresponding to the area outside the dotted circle and within the solid circle in Figure 5), such as the location of terminal B shown in Figure 5. At this time, the terminal uses the second target as the measurement target for advance measurement.

[0091] In a specific implementation, the configuration information may include multiple threshold intervals, and different threshold intervals correspond to different measurement targets. Accordingly, step S102 may specifically include: obtaining a measurement result for the primary frequency cell; and measuring the measurement target corresponding to the threshold interval to which the measurement result belongs.

[0092] For example, the configuration information may include the following configuration: [threshold 1, threshold 2] corresponds to the first target, [threshold 2, threshold 3] corresponds to the second target, and [threshold 3, threshold 4] corresponds to the third target. The farther away from the base station of the primary frequency cell, the smaller the values ​​of thresholds 1 to 4.

[0093] Furthermore, the terminal determines the corresponding measurement target based on the interval in which the measurement result falls. For example, if the RSRP value obtained by the terminal from measuring the RS sent by the base station of the primary frequency cell falls within [threshold 2, threshold 3], the terminal measures the second target. For another example, if the RSRQ value obtained by the terminal from measuring the RS sent by the base station of the primary frequency cell falls within [threshold 1, threshold 2], the terminal measures the first target.

[0094] In one specific implementation, the measurement target can be configured based on the TRP group. Specifically, at least one measurement target can include multiple TRP groups. Further, the configuration information can include a second threshold, which can be understood as a trigger threshold for determining a specific TRP group as a measurement target.

[0095] Correspondingly, step S102 may specifically include: obtaining a measurement result for at least one TRP; and measuring the sending and receiving point group to which the TRP having the measurement result higher than the second threshold belongs.

[0096] For example, the terminal normally measures neighboring cells in an inactive state or a non-connected state. When the signal quality of the TRP of a certain neighboring cell is measured to be higher than the second threshold, the terminal can measure the TRP group to which the TRP belongs.

[0097] In a specific implementation, the measurement target can be accurately configured according to the terminal location and network layout. In other words, different measurement targets can be configured based on the terminal's location.

[0098] Specifically, the at least one measurement target may include a third target, and the third target is determined according to the positioning information of the terminal. For example, the terminal may report positioning information when in a connected state, and this action may be performed before step S101.

[0099] Furthermore, step S102 may specifically include: measuring the third target. In other words, in this example, the network accurately configures a most suitable measurement target (ie, the third target) according to the positioning information of the terminal, and the terminal directly measures the third target when performing measurement according to the configuration of the network.

[0100] In a typical application scenario, the network layout within the primary frequency cell is shown in Figure 6. Assume that terminal C reports positioning information at the illustrated location. In response to receiving terminal C's positioning information, the network can configure a third target closest to the reported location of terminal C as a measurement target for terminal C. Accordingly, terminal C performs advance measurement using the third target as the measurement target.

[0101] This example solution may be applicable to a terminal in a connected state, or a terminal with low mobility performing measurements in a non-connected state.

[0102] In one specific implementation, the network can configure two sets of measurement target configurations. Different measurement target configurations use different logic when determining measurement targets based on location, corresponding to different terminal movement speeds. When the terminal moves quickly, the measurement target can be determined according to one set of measurement target configurations; when the terminal moves slowly, the measurement target can be determined according to the other set of measurement target configurations.

[0103] Specifically, the configuration information may include a third threshold, which may be understood as a triggering threshold of the measurement target configuration adopted by the terminal handover.

[0104] Furthermore, the at least one measurement target may include the third target described in the above embodiment. Step S102 may specifically include: in response to the moving speed being lower than or equal to the third threshold, measuring the third target.

[0105] Furthermore, the at least one measurement target may include a fourth target associated with the measurement results in the primary frequency cell and / or the neighboring cell. Accordingly, step S102 may specifically include: in response to the moving speed being greater than or equal to the third threshold, measuring the fourth target.

[0106] That is to say, when the terminal moves slowly, the network directly measures the third target configured according to the positioning reported by the terminal. Specifically, the network configures the third target in the terminal connection state according to the terminal's position, and when the terminal migrates from the connection state to the non-connection state or the inactive state, the third target is retained as the measurement target for advance measurement; or after the network migrates the terminal from the connection state to the non-connection state or the inactive state, the third target is configured, and the terminal performs advance measurement based on the third target as the measurement target. When the terminal's moving speed becomes faster, it switches to the fourth target configured according to the measurement results of the terminal in the primary frequency cell or the neighboring cell. In one embodiment, when the terminal's moving speed is greater than a certain threshold (for example, the third threshold), it switches to the fourth target, where the threshold can be configured by the network or implemented in a predefined manner.

[0107] In some embodiments, the fourth target may include the first target / second target described in the above embodiment. For example, when the terminal reports positioning information in a connected state, the configuration information sent by the network to the terminal may include: a third threshold, a third target (for example, it may be the TRP closest to the positioning location of the terminal), a first target (for example, it may be a TRP with a relatively light current load in the primary frequency cell and a relatively close distance to the base station of the primary frequency cell), a second target (for example, it may be a TRP with a relatively light current load in the primary frequency cell and a relatively far distance to the base station of the primary frequency cell) and a first threshold.

[0108] The terminal measures the third target during a period in which its own moving speed is lower than the third threshold, and subsequently reports the measurement result according to the advance measurement mechanism.

[0109] If the moving speed of the terminal increases to above the third threshold, the first target or the second target is selected for measurement based on the comparison result of the measurement result in the primary frequency cell and the first threshold.

[0110] In some embodiments, the fourth target may include the multiple TRP groups described in the above embodiments. For example, when the terminal reports positioning information in a connected state, the configuration information sent by the network to the terminal may include: a third threshold, a third target (for example, the TRP closest to the terminal's positioning location), multiple TRP groups, and the second threshold.

[0111] 7 , at time t1, the terminal's moving speed is lower than the third threshold. At this time, the terminal measures the third target and subsequently reports the measurement result according to the advance measurement mechanism.

[0112] If the terminal moves at high speed after time t1 and moves to the position shown in Figure 7 at time t2, the terminal no longer measures the third target, but selects the TRP group (for example, the fourth target shown in Figure 7) whose measurement result is greater than the second threshold based on the neighboring cell measurement results for measurement.

[0113] In a specific implementation, the advance measurement method of this embodiment may further include the step of: reporting the measurement result of the measurement target associated with the current location after the connection or data transmission is restored. This step may be performed after step S102.

[0114] Specifically, the terminal may move continuously or intermittently during a non-connected or inactive state. During this period, the terminal continuously performs the steps described in the above embodiment to measure the corresponding measurement target based on its own location. After resuming connection or data transmission, the terminal may preferably report a measurement report for the measurement target corresponding to the current location.

[0115] In one variation, the advance measurement method described in this embodiment may further include the step of: reporting the most recent measurement results obtained within a recent preset period after the connection or data transmission is restored. This step may be performed after step S102. Specifically, it may be combined with the enhanced advance measurement mechanism in R18. After the connection or data transmission is restored, measurement results for the measurement target associated with the current location, obtained within a timer range, are reported.

[0116] Therefore, this embodiment provides an enhanced advance measurement mechanism that configures different measurement targets based on the terminal's location. The terminal uses the different measurement targets and locations configured by the network, combined with its current location, to determine the frequency or cell that needs to be measured. As a result, in an inactive or disconnected state, the terminal can accelerate the recovery of multi-cell operation through advance measurement, which helps reduce terminal power consumption. In an active state, the measurement mechanism can also be enhanced to reduce terminal power consumption.

[0117] FIG8 is a flowchart of an advance measurement method according to the second embodiment of the present application.

[0118] This implementation scheme can be applied to 5G NR scenarios as well as 6G communication scenarios.

[0119] In a specific implementation, the communication method provided in the following steps S201 to S202 can be executed by a chip with communication functions in a network device, or by a baseband chip of the network device. The network device can include a base station, such as a base station of a primary frequency cell.

[0120] Specifically, referring to FIG8 , the advance measurement method of this embodiment may include the following steps:

[0121] Step S201: Send configuration information, where the configuration information includes at least one measurement target, and the measurement target is associated with a location;

[0122] Step S202: Receive a measurement report.

[0123] Those skilled in the art will appreciate that steps S201 to S202 can be considered as corresponding execution steps to steps S101 to S102 in the embodiment shown in FIG4 , and that the two complement each other in terms of specific implementation principles and logic. Therefore, the explanation of the terms in this embodiment can refer to the relevant description of the embodiment shown in FIG1 , and will not be repeated here.

[0124] In a specific embodiment, the configuration information further includes a first threshold, and the at least one measurement target includes a first target and a second target. If the measurement result of the primary frequency cell is greater than or equal to the first threshold, the measurement report received in step S202 is a measurement result for the first target; otherwise, the measurement report received in step S202 is a measurement result for the second target.

[0125] In a specific embodiment, the configuration information further includes multiple threshold intervals, and different threshold intervals correspond to different measurement targets. Accordingly, the measurement target targeted by the measurement report received in step S202 corresponds to the threshold interval to which the measurement result for the primary frequency cell belongs.

[0126] In one specific implementation, the at least one measurement target includes multiple transmission and reception point groups and a second threshold. Accordingly, the measurement target for the measurement report received in step S202 is the transmission and reception point group to which the transmission and reception points having measurement results higher than the second threshold belong.

[0127] In one specific implementation, before executing step S201, this embodiment may further include the step of receiving positioning information. The at least one measurement target configured in step S201 includes a third target, which is determined based on the positioning information of the terminal. Accordingly, the measurement report received in step S202 is a measurement result for the third target.

[0128] In one specific implementation, the configuration information further includes a third threshold, and the at least one measurement target includes: a third target determined based on the terminal's positioning information; and a fourth target associated with measurement results in the primary frequency cell and / or a neighboring cell. Accordingly, based on the terminal's moving speed, the measurement report received in step S202 is a measurement result for either the third target or the fourth target.

[0129] In a specific implementation, step S202 may specifically include the step of receiving a measurement result of a measurement target associated with the current location, reported by the terminal after the connection or data transmission is restored.

[0130] Alternatively, step S202 may specifically include the step of receiving the latest measurement result obtained within a recent preset time period and reported by the terminal after the connection or data transmission is restored.

[0131] In a specific implementation, after step S202, the network may continue to perform subsequent steps related to the advance measurement mechanism, such as performing an RRC reconfiguration process according to the measurement result reported by the terminal, so that the terminal can accelerate the recovery of CA or DC operation.

[0132] Therefore, the network configures different measurement targets according to the terminal location, so that the terminal can autonomously and accurately determine the appropriate measurement target for measurement based on the current location.
